The power pack was connected to and outlet but I made sure that I connected the wires to the dc slot in the power pack. The mass could have been 2kg as the teacher told us the metals were made to be exactly 1kg yet no one checked. I doubt this though as the metals felt more around 1kg than 2kg...
the figure was written on the heater (something like 12V will cause the heater to emmit 50W). During class the prof just said that we would have something to go home and think about, he didnt want to tell us (although I doubt he knew). A mistake in the procedure would make the most sentence, yet...
yup :) that's completely correct
I made a mistake again (sorry), by typing half instead of whole. Everyone in the class was around +-100 what I got. The power was DC, 12V.
(Oh, and thanks for your time and effort)
sorry my fault, I misworded the thing https://www.physicsforums.com/images/smilies/frown.gif .[/URL] What I ment was the power pack was left off so that the thermometer could adjust itself to the original temperature and then later turned on with the stopwatch, emmiting 50W until the temperature...
